Irequire a wiring diagram and pin-out for 1nz-fe, specifically for the variant available in axio (E140). I've been digging the internet for some time but havent found much specifically for the variant. I would be very grateful if anyone can help me source the wiring diagram / pin-out for the said engine / ecu. Thank you.

I've tried searching by vitz rs, yaris and corolla. Will give premio a try too. Please do let me know if you find anything related to it. What i've mostly come across is stuff for the older model too.

I do not have the exact pinout for it but even if i get a pinout, that would be good enough. I'm planning for a 1nz swap so doing my homework before plunging into it because me and a friend will be doing the wiring bit ourselves.

I havent purchased the engine, ecu and wiring yet but will be heading down to the place on saturday inshaAllah. Here is one of the ecus that was available when i went there last week. This one's from a 4wd of course but will be looking for a 2wd one. As per my knowledge, these ecus are sealed and would be a nightmare to open i could be wrong though.

The kabariyas say that the wiring would be uncut but I dont completely trust their wiring hence the need of wiring diagrams in case the wiring has been fiddled with. If it comes to that, tracing the wires through continuity would be the only option.

Scanner revealed a P0335 error code for the crankshaft position sensor. I reset/erased the code a few days ago and so far it has not reappeared. Engine is running quite smoothly again. I have ordered a replacement sensor from eBay.

Last night I kept looking at another section of an online workshop manual and that engine diagram was indicating that the sensor was near the crankshaft pulley. Then looked at some pictures posted by eBay sellers for the 1NZ-FE engine.

I had previously looked at this YouTube video and discounted it. Now confirmed that it does correctly show the location for the Yaris crankshaft sensor as being at the rear of the crankshaft pulley and bolts into the timing belt cover.
